Hello riu, this is my first grow and i just want to make sure i get these small details down. i'm sure this question has been asked a bunch, but i can't seem to find an exact answer on any forums. So i have a 4x8" CF attached to the S&P TD100 fan right now. The set up is CF -> Fan -> Exhaust. I have a 150w HPS set up (no cool tube and built in ballast) with 120mm case fan with 40~cfm as intake. Box dimensions are 36Hx18.8Wx21D". I put 1/2" styrofoam along the walls as panels to keep down noise, and since i couldn't find any mylar where i live, i used reflectix to line the cab, but recently ordered b/w 6m poly to put along the doors and floor to keep it light tight and clean. I've only tested the box once so far and by the looks of it with lights on it runs 85F~ with 39%H. I know that ideal temp is mid 70's and RH 40-50?. I've also ordered a 5" O2 fan for some air circulation. So basically my question is, are my temps too high b/c of all the insulation, or is it b/c my fan isnt pulling enough air b/c of the filter or my case fan sucks o.o idk really lol. And would installing the O2 fan bring temps down at all? Any help would be great thanks!
